When running iperf3 between devices on my LAN I am having an issue with my network throughput. I have a Beelink EQ12 with Intel i225v chipest and when connected to a 10GbE switch via SFP+ tranceiver I am able to get 2.5GbE throughput on the upstream to iperf3 servers but when going downstream it is showing it being capped at 1GbE. I have updated to the latest kernel and even tested a 2.5GbE USB-C adapter and still having the same issues.
